I have completely cut out wheat about 6 months ago and it has improved my symptoms more than any other remedy. When my POIS symptoms first began 10 years ago I noticed some bloating. I now believe this was inflammation of my intestines, which lead to impaired digestion and malabsorption of nutrients. Since I cut out wheat(perhaps gluten) my symptoms improved greatly, but I developed a flatulence problem. Then I cut out most fiber and animal products, which helped decrease the gas. Now I eat mostly potatoes, white rice, oatmeal, beer, and most fruits and veggies.
I am aware that oatmeal and beer may contain small amounts of gluten, but I seem to tolerate them fine. In fact beer seems to improve my digestion.
I've been taking peppermint oil capsules to further aid digestion and decrease the smell of this new flatulence problem. -edit 10/30/16- The capsules also contained ginger oil and fennel oil. I now have reason to believe the ginger oil was helping me while the peppermint oil was hurting me.
I'm curious if anyone else experienced anything similar regarding wheat or gluten.
